Answer:
It has infinite solutions.
Answer:
1st option
Step-by-step explanation:
The equation for the 2nd option will be y = 1/x which is a hyperbola
The equation for the 3rd option is I'm unsure because it is not linear as it does not have the same jump between the y values
The equation for the 4th option is not linear as it does not have the same jump between the y values
Hope this helped and have a good day
Answer:
x=-1, x=3 e x=2i, x=-2i
Step-by-step explanation:
Solve for x over the real numbers:
x^4 - 2 x^3 + x^2 - 8 x - 12 = 0
The left hand side factors into a product with three terms:
(x - 3) (x + 1) (x^2 + 4) = 0
Split into three equations:
x - 3 = 0 or x + 1 = 0 or x^2 + 4 = 0
Add 3 to both sides:
x = 3 or x + 1 = 0 or x^2 + 4 = 0
Subtract 1 from both sides:
x = 3 or x = -1 or x^2 + 4 = 0
Subtract 4 from both sides:
x = 3 or x = -1 or x^2 = -4
x^2 = -4 has no solution since for all x on the real line, x^2 >=0 and -4<0:
Answer: |
| x = 3 or x = -1
Answer:
Step-by-step explanation:
C.
The equatorial radius of Saturn is approximately ten times that of Earth.
The ordinal is identical
The exponent of 10 is 4 - 3 = 1 greater for Saturn than for Earth
10¹ = 10 times
